It is possible. But I think you have to do the session handling yourself:

session_name('foo');
// start first session
session_start();

// …

// close first session
session_write_close();

session_name('bar');
// obtain session id for the second session
if (ini_get('session.use_cookies') && isset($_COOKIE[session_name()])) {
    session_id($_COOKIE[session_naem()]);
} else if (ini_get('session.use_trans_sid') && !ini_get('session.use_only_cookies') && isset($_REQUEST[session_name()])) {
    session_id($_REQUEST[session_naem()]);
}
// start second session
session_start();

// …

But note that you might do some of the other session handling things like cookie setting as well. I don’t know if PHP does this in this case too.
